What would you do if you discovered that your partner wasn't who they said they were - they were in fact an undercover police officer and had used their relationship with you as a way to obtain intelligence. Unbelievable right? Apparently not. We've been glued to our screens watching BBC's latest six part drama, Undercover, which sees a policeman assume the identity of a deceased individual and inveigle his way into the life of his now wife. It is based on the true stories of women who have found themselves in exactly that situation. Of course if only the deceased person had been registered on Halo, our identity fraud screening file; the protagonist would have found it very difficult to steal his identity - but then there would be no programme!

Interestingly the series is very timely since the Pitchford Inquiry is soon to be heard. It investigates the police's undercover infiltration of 460 political groups since 1968. It is thought that there are still significant numbers of officers in place and in relationships with partners who remain oblivious.

Deceased identity fraud is not just the domain of undercover officers - but also criminals. Our most recent research reveals that it is considered one of the easiest crimes to commit and is consequently now one of the UK's fastest growing crimes costing millions every year. Halo enables organisations to stop fraudsters obtaining credit, goods and services in the name of someone that has passed away.
